UI Toolkit for Meta Ray-Ban Display materials

ContainerMaterial is the rendering infrastructure shared by StaticContainer, Container, Surface, and compatible higher-level components. Treat those three primitives as equal material hosts; none is the default owner merely because the API type is named ContainerMaterial. A material paints ordered visual-effect layers around live DOM content and responds to NONE, DEFAULT, FOCUSED, and PRESSED visual states as directed by its host.

• references/material-architecture.md for layers, placement, state, canvas, shapes, cloning, and custom implementation.
• references/color-gradient-recipes.md for color selection, themed materials, gradient steps, and review.
